Case Study: BA and No.4 Stainless Steel Plates for Appliance and Elevator Panel Manufacturing
Case Study: BA and No.4 Stainless Steel Plates for Appliance and Elevator Panels
A manufacturer of household appliances and elevator interior panels needed stainless steel plate with flawless, consistent surface finishes. Any scratch, colour variation or roll mark would be immediately visible to end users, damaging the brand. The company partnered with our team to secure BA and No.4 finished plates of dependable quality.
Customer Background
- Industry: Appliances and elevator interior fit-out
- Products: Refrigerator panels, oven fronts, elevator doors and cabin walls
- Material: Grade 304 plate in BA and No.4 finishes
- Priority: Aesthetic consistency and defect-free surfaces
The Challenge
Visible surfaces leave no room for error. Inconsistent finishes from multiple suppliers caused mismatched panels, rejected batches and reputational risk. The customer required a single, reliable source capable of delivering identical appearance over many repeat orders.
Our Solution
We produced BA and No.4 plates on controlled lines to guarantee uniform grain and brightness, and protected every sheet with adhesive film for transport. Reference samples were approved in advance, and we reserved production capacity so that repeat orders matched the original appearance precisely.
Results
| Metric | Before | After |
|---|---|---|
| Surface consistency | Variable | Uniform |
| Rejected batches | Common | Rare |
| Brand complaints | Occasional | None |
| Supplier count | Multiple | Single trusted source |
Why It Worked
Finish consistency is everything for visible products. By consolidating supply with one quality-focused partner, the manufacturer eliminated mismatches and strengthened its brand reputation.
Client Feedback
The purchasing manager praised the supplier's ability to reproduce identical finishes across thousands of sheets.
Finishes Considered
The customer evaluated several surface options before settling on bright annealed (BA) for appliance front panels and No.4 brushed finish for elevator doors and cabin walls. BA offered a clean, reflective look ideal for kitchens, while No.4 provided a sophisticated satin texture resistant to fingerprints and daily wear. Both were produced to strict appearance tolerances.
Cost and Efficiency
Consolidating to a single supplier reduced administrative overhead, simplified quality control and lowered the total cost of ownership despite competitive unit pricing. Faster, more predictable deliveries also shortened the customer's working capital cycle and improved its on-time performance to end clients.
Ongoing Cooperation
We continue to reserve production capacity and maintain approved reference samples, ensuring that every future order matches the original appearance. This long-term approach protects the customer's brand consistency as its product range expands.
Reliable finishes, delivered on time, have become a quiet but powerful competitive advantage for the manufacturer.
This case shows how the right surface finish partner can elevate both product quality and brand reputation in highly visible markets.
